Patented July 19, 1938 TEbS A ES PATENT OFFICE This invention relates to new and useful improvements in heaters;

One object of the invention is to provide an improved heater so arranged that-more efliciency .l:5 may be obtained in heating a liquid and so constructed that a constant supply of heated liquid is available.

An important object of this invention is to provide a heater having a heating chamber #10 through which liquid is circulated, there being a series of improved baffles within the chamber whereby incoming cool liquid iscaused to travel through an elongate or circuitous path and also whereby the flow of said liquid through the chamber is retarded, thereby resulting in positive heating of the liquid as the same flowsthrough the chamber. 11 I i I A further object of the invention is to provide an improved heating chamber having res- 20 ervoirs or pockets-therein through which the water to be heated is circulated, said pockets trapping the liquid therein when theli'quid is not flowing, whereby the incoming cold liquid will admix with the hot liquid standingin said pock- 2 ets to make faster heating of the incoming liquid, and also whereby a constant supply of heated liquid ispresent in the chamber at all times.

A further object of the invention is to provide an improved heater so constructed that the other 30 surface of said heater, to which heat is applied,

has an increased heat absorption'surface which makes for maximum heatingwith minimum heat application. I Another object of the invention is to provide 35 an improved heaterwhich maybe readily connected in a water, or otherliquid line, the heater itself being capable of easy assembly or disassembly, and having a minimum number of parts.

A still further object of the invention is to provide an improved heater having its heating chamber divided into two sections both of which communicate with the liquid inlet whereby the liquid to be heatedmay pass to either one or the other of said sections; .each section being so .45 constructed that the liquid entering the same is circulated therethrough and: conducted to the outlet whereby the liquid isheated in flowing through one of the sections and the necessity of flowing the liquid through the entire area of 50 the heating chamber is eliminated, which reduces the time necessary to heat the liquid. i

A construction designed to carryout the invention will be hereinafter-described, together with other features of the invention. .55 The invention will be more readily understood 1 within the chamber.

6, Claims. (c1. zg-zqs) I from a reading of the following specification and by reference to the accompanying drawings, in

' which anexample of the invention is shown, and wherein:

Figure-[1 is a plan view of the'interior of the d e" l v Figure 2 is a transverse, sectional view taken on the line 2-2 of Figure 1, 1

Figure 3 is a side elevation of the device, and

Figure 4 is an elevation showing the device connected in a line.

In the drawings, thernumeral l0 designates circular casing having a bottom and an outwardly extending peripheral flange I2, said flange being provided with. internally screw-threaded 11'5 ears l3. An axial collar l4 is preferably made integral with the bottom H of the casing and extends upwardly to the same plane as the top of the flange l2. A cover member 15 is placed 'on top of the flange l2 and engages the collar Hand is secured to the flange by bolts IBIwhich pass through the cover and are screwed into the with the flange l2 and has an inlet pipe 18 connected therein. Outlet ports l9 are provided in v the bottom ll of the casing being located one on each side of the inlet I'I. These ports l9 are connected by a passage Hi from which extends "a central outlet 20 and a suitable outlet pipe- 2| is attached to the outlet 20. From the above it will be seen that liquid; introduced through the pipe 18 will flow through the chamber and pass therefrom through the pipe [9. For elongating the travel path of the liquid through the chamber a suitable bafiling is disposed 40 g This bafiling includes a V- shaped baflle or deflecting plate 22 located at the mouth of the inlet in the chamber A and the "point of this baflle is in alinement with the axis of the collar I4. The walls of the bafile form 'a pocket B open at its innerend' Extending inwardly toward the center of thechamber from the sides of the mouth of the inlet are divergand spaced from the walls 23 are deflecting plates '24 which deflect liquid into the pocket B; uExtending from the outer ends of the walls 23.and

preferably integral therewith are arcuate members 25 which have the same center as the collar 14. The members 25 have a greater are so as to be spaced from the collar, whereby passageways around said collar are formed. Diverging radial baffles or walls 26 extend from the arcuate members 25 and have their outer ends terminated short of the flange l2. The extreme outer end of each wall 26 is bent upon itself at substantially a rightangle so as to form an overhanging lip 26'. Located between the diverging'walls 26 is a V-shaped baffle 21 having its point in alinement with the axis of the collar l4, and passageways C are formed'be tween the walls 26 and the walls of the LV shaped bailie. The outer ends of the bafile are terminated short of the flange and bentinw'ard- 1y toward each other andobviously apocket C."

is provided within the bafile. A deflector 21f ex-r tends inwardly into the bafile centrally thereof and; acts j to deflect liquid into 1 the pocket 0. Thus it will be seen that liquid. introduced: into *thechamber A'will strike the member 22 "and flow along the passageways B and the deflecting plates 24-willcause part of the liquid to flow into the pocket 3 and admix with' liquid standing therein. sometliquid willflow around the collar l4 and'again be separated into two streams by the v-shap'ecl bafiie 21jand flow through-the divergent passageways C toward the peripheral flange l2. A portion of the liquid flowing from the passageways will enter the pocket C;

-;;It will be seen that the flow of liquid is divided .into'two distinct streams by the V-shapedbaflle 21, one; stream flowingthrough the chamber -A ina counter-clockwise direction and the other streamflowing in a clockwise 'direction. Both streams of liquid will be taken through a like course and, therefore, a description of the f path of only one stream is considered necessary. After the liquid has passed through the passageway C itwill strike the. peripheral flange |2 whereby-a tportiongof said liquid isldirected back towardithe V-shaped bafile 21 and into the pocket C therein.

The'remainder or major portion will flow in a clockwise direction along the periphery of the chamber. streamof liquid will flow into ya pocketD which is formed by the member :26

and by a 'bailie 28 which extends outwardly from the arcuate member-25; The extreme outer end of the 'bafiieZB is bent inwardly to overhang the pocket D and is located closer to the flange l2, -or

.to the periphery-of the chamber than is the overhanging2lip 26"of the member 26, whereby said baflle extends beyond the member 26. With'such arrangement; the flowing liquidstrikes the outer end of the baflle' beneath the inturned extension thereof, and is directed inwardly into the pocket D. To further direct the liquid-into the pocket D,- an'inwardly extending deflector 3| is prefer- .ably integral with the flange l2 and is located substantiallylof the center of the pocket. Therefore, the liquid flowing from'the passage C is directed into the pocket Dand is circulated therethrough.. l 1

=Manifestly, the liquid is whirled: or agitated by its flow through the pocket. D and then escapes its clockwise travel lDfo'rmediby the member 26land tame-2a. "Pocket G is formed by the baffle 28 of pocket D and baflle 29 of pocket E, likewise pocket I is formed by the baflles that formed the pockets E and F, as is clearly shown in Figure 1. A deflecting member 3| is located at the mouth of each pocket so as to direct liquid thereinto. Thus it will be seen that the liquid is deflected into each pocket and therefore the flow of the liquid is retarded. After the liquid escapes from pocket F it will strike: abaflle 32 and flowaround it and into the outlet port l9'whereby the-liquid is conducted out through the outlet 20 and. outlet pipe 2 I.

- For greater heat absorption there is provided concentric rings 33 integral with the bottom ll of the casing. The rings provide an increased area which makes for maximum heating with minimum heat application.

..iForiheatingi-theidevice, I have shown in Figure 4 a burner 35 which is connected in a feed line 36,"said' feed line is provided with a valve 31, said vvalve-31sconnected into; the control means -38 in the fluid inlet pipe IB. This" type of burner has :provedsufiicient but: obviouslylany type of burner -desired mayybeused. s v

'In operation the liquid is supplied tothe chamzgberAiby: the-inlet l-l', said liquid will strike the baffle 22 and pass around, some liquid going into t'he'pocketB caused 'by thedeflecting plates 24 and thenpass-{aroundzthe collar l4 and out through the passageways C. Manifest-1y, the liq- -uid can flow in a'clockwise or a counter-clockwise direction; .Aiterqpassingthrough the passage or channel C said: liquid will be deflected into each .of the p'ockets and the flow of said liquid will be retardedrby thissystem of baffling which holds .1

the liquidwithin the chamber atsufiicient length of time to efiiciently heat the same. The heated liquid escapes-from the chamber through the port! and the outlet 20. I

ltwill be seen that the wausor the baflles will 1 be heated andwill'tend to heatvthe incoming cool :liqui'd'. The pockets =formedin the heater will 'holdsome of the'liquid when-the-device'is not operative, whereby; thisi trapped (liquid is heated to'a much higher temperature than is usually necessary. 1=jTherefore,-;when circulation of the liquidis again started; thecool incoming liquid will contact thehotbafiles and will admix with the trapped-"overheated liquid within the pockets,

which-will resultin a quicker or more rapid heat- :ing of thejcool liquid.

v'iIt is. pointed out-that by this system of bafiling the introduced liquid is divided into two streams :gandeachi stream is caused toflow -overonly'one half 'ofthe heater, thereby; the time necessary 'for. liquid to pass through the heating chamber to'be suflicientlyheated is greatlyreduced.
